of Wiirtemberg,Germany, have invented ce1'- ingApparatuS, of `which the following is a specification.

The object of `my invention is to provide a cooling and condensing apparatus especially tity of water can be cooled in a very small apparatus."` i

My invention is especially applicable to the cooling apparatus'used on automobile explosion-motors. v

Referringtothe accompanying drawings, Figure 1 is a frontview of one form of cool- Fig. 0 is a Fig. 3 is a section on Fig. 4 is an enlarged plan View ot' Fig;-` l. the line 3 3, Figfl.

sectional View offa portion of Fig. 1. Fig. 5 is a sectionon thc line 5 5, Fig. 4. Figs. G,

7, S, and 9' are views illustrating different forms of tubes that may be used; and Fig. l0 is a view showing the preferred form of cool ing apparatus used on automobiles.

The ooolingandoondensingapparatusillustrated in Figs. 1 to 5, inclusive, consists of'a frame A having a network o Aat each end, as shown in Fig. 5. This network in the present instance consists of wires which may be interwoven, as shown, or may simply be arranged to cross eachother. The wires are so strung on the frame as to form a series of quadrangular openings of uniform size.

B represents tubes quadrangular in cross-` section, which snugly tit the quadrangular openings formed by the wire" mesh. `These tubes, as clearly shown in Figs. 3 and 4, extendithrough the quadrangular openings formed by the interlacing of the wiresa a, and thewiresspace these tubes sufficiently so `that there will be very narrow vertical and horizontal channels between each of the tubes. When the tubes are in position, the ends of the tubes are soldered or otherwise secured to the wires forming the screen or network,

and a cooling vessel is thereby formed which is water-tight and so formed that when water is passed into the apparatus through thepipe e it circulates throughout the entire body of the cooling apparatus and escapes through the pipe f. The water as it passes through the apparatus must pass in very thin streams between the two surfaces of each tube," `as shown clearly in Fig. 4, so that an extended cooling-surface is thus afforded with comparatively little expense.

The water after it passes from the cooling apparatus is cooled sufficiently for the purpose for which it is intended, and the air can pass rapidly through the apparatus without interruption.

The wires forming the screen maybe round or Hat, as desired,and may be of any weight or thickness, depending upon the size of the cooling apparatus and the amount of space desired between each tube.

The tubes B may be spaced in any other manner besides that shown in the drawings, and instead of forming the screen by a wire network the screen can be produced by punchiug holes in a sheet of metal and fastening the tubes to this frame by expanding them, or the pipes may be fianged at each end and secured together at the ends, so as to form narrow channels between the pipes. By each one of these means I obtain the result-that is, the separation of the tubes byl narrow channels through which the water to be cooled can pass. The tubes in the present instance being quadrangular in cross-section enable me to make both vertical and horizontal narrow channels, and al] the channels will be uniform.

Instead of using a quadrangular tube, as shown in Fig. 1, triangular tubes may be used, as shown in Fig. 6. In this instance a diagonal wire a' is used, and thus the triangular tubes are separated, so as to form narrowpassage-ways for the passage of the liq-` uid to be cooled.

In Fig. 7 I have shown another form, in which triangular tubes are used, and in Fig. 8 I have shown a form in which the tubes B are divided by a series of partitions b. In

this instance the wires simply separate each tube-section, forming long vertical and short transverse channels.

In Fig. 9 I have shown a modification in which the principle shown in Fig. 8 is used, only the partitions in this instance form triangular passagesinstead of the quadrangm lar passages shown in Fig. 8.

" In Fig. l() I have shown the external form of a cooling and condensing apparatus especially adapted for automobile use. It will be seen that the end portions of the frame A are formed so as to leave a space between these and the said tubes, thus allowing water entering the apparatus through the pipes c to distribute itself uniformly through. the various passages, said water also passing between the sides of the frame and the tubes extending along said sides, being finally collected and passing out through the openingf.. In the construction shown in Figs. 8 and 9 Where each tube is divided into a series of spaces by partitions b these partitions will act as conductors and will further act as a means for strengthening the tubes.

It will be understood that the apparatus;A

can be used for cooling any fluids; but it is especially adapted for automobile work.

By the construction above described I am enabled to provide a cooling and condensing apparatus which will take up very little room and which will have a very large surface over which the fluid to be cooled can iiow and there is no obstruction to the free Ipassage of the air through the apparatus.

I claim as my invention- 1. The combination of aframe having screens at each end formed by wires crossing each other and tubes extending i' rom one screen t-o the other, said tubes being secured to the Wires and forming a chamber/for the duid to be cooled, substantially as described.

2. The combination of a frame having an inlet-pipe at one end, and an outlet-pipe at the other end, a series of wires crossing each other at each end of the frame forming supports, With prisrnatically-shaped tubes eX- tending from one side of the frame to the other and separated by the wires, the wires spacing the tubes so as to form narrow channels for the passage of iuid through the apparatus, substantially as described.

3. The combination yin a cooling apparatus of a frame, a screen at each end thereof formed by wires crossing each other, the meshes ofthe screen so formed being quadrangular in form with quadrangular tubes extending through one screen to the other and secured to the same, the side members of the frame extending a certain distance away from the said tubes thereby forming a distributing-chamber, andinlets and outlets to the chamber thusvformed, substantially as described.

In testimonywhereof I have signed my name to thisspeciiication in the presence of two subscribing witnesses.
